Comment on How does data sent over the internet know where to go?

Packet headers.
A packet is like a sealed mailing envelope. Its headers are like things written on the face of an envelope, including an address. Chunks of data on the internet are so many letters in these envelopes, carried and delivered by a network of other computers.

To expand on this: every website that you go to online (i.e. www.google.com) is backed by an IP address.

And the Domain Name (Google.com) get’s converted from words we understand to the IP address. This is the Domain Name System, or DNS. Everyone on the network agrees that Google.com equals 142.250.189.174. If that address changes, the change gets passed through the system until everyone agrees on the new IP address. DNS is how your computer learns the address.
